Oil India Ltd (OIL) and TotalEnergies have formed a strategic partnership to accelerate exploration in India’s deep and ultra-deepwater offshore basins. The collaboration aims to enhance India’s offshore energy prospects through advanced technology, global expertise, and joint evaluation of high-potential hydrocarbon blocks.
Focus on Deep and Ultra-Deepwater Basins
OIL announced that the partnership covers ultra-deepwater blocks in the Mahanadi and Krishna–Godavari (KG) basins. These blocks were secured by OIL under the ninth round of the Open Acreage Licensing Policy (OALP). Additionally, both companies will evaluate exploration opportunities under the ongoing OALP Round 10 and future bidding rounds. The agreement underscores OIL’s strategy to bring in international expertise for technically challenging frontiers.
Technology Service Agreement Signed
On 19 November 2025, OIL and TotalEnergies signed a Technology Service Agreement in New Delhi. The agreement enables OIL to tap into TotalEnergies’ proven capabilities across the deep and ultra-deepwater exploration value chain. This includes seismic data analysis, geological interpretation, and drilling support for stratigraphic wells mandated by the Government of India. With this partnership, OIL aims to strengthen its offshore portfolio and accelerate exploration timelines.
Support for Offshore Drilling Initiatives
TotalEnergies will assist OIL during stratigraphic and test well drilling in offshore Category II and III basins. This technical support will help OIL reduce exploration risks, improve reservoir understanding, and fast-track decision-making for future development.
Collaboration in the Andaman Basin
Both companies will also work together on the appraisal programme of a major gas discovery in the shallow offshore blocks of the Andaman Basin. OIL has already announced significant natural gas finds in the region, considered crucial for India’s long-term energy security. The company won two exploration blocks in the Andaman Basin during OALP Round 3 in 2020.
Strengthening India’s Energy Security Goals
Ranjit Rath, Chairman and Managing Director of OIL, emphasized that collaborating with an international oil company helps improve seismic analysis and gives OIL access to advanced global experience. He noted that evaluating offshore blocks is a key component of the partnership. Future drilling activities could be jointly undertaken once exploration risks are sufficiently mitigated.
Global Expertise to Drive Offshore Growth
Industry experts highlight that India’s push for energy security and reduced import dependence requires deeper exploration of offshore basins. Given the complexity of deepwater operations, global partnerships such as the OIL–TotalEnergies collaboration are essential for accessing cutting-edge technologies and operational know-how. As reported by msn.com, the collaboration marks a significant step in India’s efforts to unlock new offshore resources and strengthen the country’s long-term energy landscape.
